This invention relates to an ignition apparatus suitable for 4firing the charges 1n an internal combustion engine. It has been found that the power of an internal combus- 5 tion engine is increased by having a plurality of sparks to fire the charges in each cylinder but this practice has not been generally followed, on account of the increased cost, however for certain classes of work two or more sparks have been utilized.

It is the principal object of my invention to provide an ignition device which is capable of producing a plurality of sparks for the purpose of increasing the power of the engine and'securing a greater margin of operative safety.

I have preferred to incorporate my invention into a magneto electric generator,

by reference to the drawings, in which Figure l is a longitudinal `vertical sectional view throughv the magneto.

Figure 2 is an end view ofthe breaker end of the magneto `butwith some of the details in connection with the distributor arranged somewhat differentlyv than in Figure 1.

Figure 3, is a View. fromthe'driving end while Figure 4, 4is a diagram of the preferred form of circuitarrangement.-

Referring now to details wherein like numbers refer to cor-responding parts in the various views, l is a frame, to which is attached the driving end plate 2, and a breaker end plate 3. Within'the frame 1, is

rotatably mounted on the usual ball bearing and the invention will. be best understood ofthe magneto with the end plate removed,

6. The armature 5, has a low tension wind-` 4nuts 27, which are .prevente with the contact 9, is'a breaker arm 10 operated by the usual cam 11 forcontrolling the current in the armature winding 7. 'The circuit breaker arm' 10 iscarried on a stud 39. Across the top of the frame 1` is a pair of magnetic members l2 and 13, which are preferably made of good magnetic ma terial. The members 12 and`13 are somewhat shorter than the distance between 4the limbs of the magnet or magnets 14,' which are. associated with polepieces 15 between winch the armature 5 rotates, so that there 1s llttle or no magnetic leakage from one limb of the magnet through the members 12 and 13, to the other limb of the magnet.

/Vhile Figure 1 shows-two magnets, it is to be understood that in the s ecification 'and claims where a magnet is re erred to, it

mea-ns either av singleor a plurality of magnets, so arranged as' to give the effect of 'one Single magnet.

Positioned on-each of. the members' 12 and 13 isa coil lstructure including `core members 16, the ends of which rest on the extremities of each of the members-12 and 13. Each of the core members 16 carrie a coil 17, which is preferablymade up a primary winding 18,1.-and secondary windf ing 19. The cores l-areheld to the members 12 and 13, by clamps 20, preferably of non-magnetic material. The clamps 20 are held in place by studs 21-and nuts 22, which are positioned on opposite ends of the coil structure. The secondary windin of each of the coils is brought out throu suitable connecters, andl carried to the istributor.

threaded through holes29, in the ends of the studs v i The tensioncurrent from one of the coils is` brought to a ydistributing finger 30,

and the liigh'te'nsion current from the other.

I eration, sparking current is enerated 'in the stationary coil is brought to ,the distributing finger 31, the lingers 30 and 31- being carried by a rotating member 32 of suitable insulating material, carried by the distribu tor gear 33, which in turn is driven by a pinion 34 on the cam end of the armature 5..

The various details entering into the distributing features of the machine, are not further describedv in detail as my invention relates, particularly to the generating features, which includes the main generating winding 7, and the auxiliary windings, `18 and 19.

The operation of my magneto electric generator will be readily understood by thel ollowing brief` description: As the armature 5 and winding 7 thereonis operated the current is generated in the winding 7 inthe usual way, due to the passage of inavnetic flux through the armature 5. This led by the circuit breaker secondary windings 1 9, an distributed to the respectivespark plugs 35 in the engine c linders. It may bevnoted in passing-that t e usual condenser 36, which is shown as carried by the armature 5- is connected across the circuit breaker points to prevent sparking thereat, also'a1 switch contact 37 is provided for shortcircuiting the winding 7, when it is desired to` stop the engine.

' It will be noted from the diagram o`f Figure 4, that the windings'18 are connected in series withl theprimary winding 7, which is the preferred way of operating the generator,'but the windings 18 themselves may be connected in parallel.

I have found that by utilizing the entire kspace on the armature 5 for a single low tension winding and arranging the lstationary coils in the manner shownand described, that I can obtain results far better thang-in anyother manner, so that two hot sparks -may be provided at most. extremely low speed of the armature 5. I have thus obtained a generator which will deliver two simultaneous sparks to each engine cylinder without the generation of one spark interfering with the generation of the other spark.

In the drawing I have shown a two spark' machinev for a six cylinder 'engine since the distributor block shown in Fig. 2, provides for twelve cables or a pair for each of six cylinders, but it is to be understood that the machinemay readily be constructed for a two s ark four cylinder, or two spark eight vcylin er, engine, etc.
